So, I watched the first episode season 3 to bring myself up to date and then the last episode of 3 for the same reason so I could better understand what was happening in the 4th season. I think my wife and I have watched 2 episodes tonight and sort of started the 3 episode of Season 4 of "the Diplomat". on Netflix. Rotten Tomatoes give it a 93% also so it has always been very well done.
However, there was supposed to be a Season 5 but I'm not sure that's going to happen or not at this point.
